Resume this action-packed LitRPG progression fantasy series, perfect for fans of The Primal Hunter, He Who Fights with Monsters, and Unbound.
Massive soul damage. Shattered skills. Recovery requires rituals.
Joe the Ritualist trusted his faction leader too much, not seeing Tatum’s blind spot before it was too late, and a catastrophic surge of Divine Energy left his Mana Channels in ruins, his skills in tatters, and his future uncertain.
With natural recovery off the table, Joe designs a way to rebuild himself from the inside out: crafting new Mana Channels and anchoring them to his body and soul through a bespoke ritual. It’ll take every one of his skills, and every last favor he’s earned.
While the price for power is steep, nothing worth doing is easy. The Ritualist decides there’ll be no more waiting. Now it’s time to work magic on a global scale, and rip what he needs right out of the World Boss’s heart.
One ritual to change the world. One to fix his fate. Both demand the fall of the Jotunn.
With over 1 million copies sold, The Completionist Chronicles is a LitRPG series packed with immersive progression, mechanic-driven character growth, and quest-based advancement. The result is a humorous fantasy adventure that feels like stepping straight into an RPG world.
Perfect for fans of the snarky narrative of Dungeon Crawler Carl, the expansive worldbuilding of Defiance of the Fall, and the clearly defined magical progression of Cradle.
Secure your copy on Audible with narration by Luke Daniels.

xHE-AAC only because with Audiobookshelf finally supporting it and iOS, Android and Windows supporting it natively it’s the highest quality format and as such the best one to share.
If you require other formats feel free to use ffmpeg to convert it to whatever you prefer.

thank you
January 15th, 2026
My audiobookshelf doesnt support it unfortunately.
v2.32.1 (12/23/2025)
January 15th, 2026
I’m using VLC, which has played m4b before, and all I get is silence
January 15th, 2026
The issue is xHE-AAC is still not fully supported by Audiobookshelf. It natively will play on mpc for me, but it doesnt show up in Audiobookshelf or Plex for that matter.
January 15th, 2026
So far the best solution is converting them back to .mp3
January 15th, 2026
I use fre:ac and LAME MP3 encoder which keeps the quality as the source.
January 15th, 2026
@redemption, thank you, your notes were very helpful
January 15th, 2026
this file has DRM still and it has USAC, and even getting it to play the audio quality is choppy and painful to listen to, OP if you use AAX audio converter you should be able to resolve these issues
January 15th, 2026
Not the OP but if you convert back to .mp3 it plays and loads fine on everything. I just did a FDK-AAC conversion .m4b to .m4b which works even better.
January 15th, 2026
thanks for the advice redemption, ended up using dBpoweramp and the FDK-AAC conversion, worked a charm :D
January 15th, 2026
My Audiobookshelf (latest version) plays .m4b files, just fine. So if there is an issue, it must be this file. Maybe, try stripping any DRM out?
January 15th, 2026
@redemption & @Friday: https://github.com/advplyr/audiobookshelf/issues/4236
So if you’re running it in Docker redeploy the container with the newest image and it should work.
@red206: I can’t find any information on Google concerning VLC’s support for xHE-AAC, though I’m not sure why you’re using VLC to play audiobooks. There are plenty of audiobooks players on Android and iOS and they all support it, in addition to having dedicated features for audiobook playback.
And for Windows if you have Windows 11 22H2 or newer you can just play it in the browser from Audiobookshelf or if you want to play it locally use foobar2000 with FDK AAC Packet Decoder: https://www.foobar2000.org/components/view/foo_pd_aac
@qazkeyzer: there is no DRM, and USAC is an audio object type (AOT 42: Unified Speech and Audio Coding (USAC) [USAC]) of the xHE-AAC codec:

https://en.wikipedia.org/wiki/Unified_Speech_and_Audio_Coding
January 15th, 2026
On a side note, thank you for letting me know about dBpoweramp, qazkeyzer!
I’ve spent a lot of time learning and building code to use ffmpeg effectively to process xHE-AAC files, and it’s nice to know that I have now a fallback product in case ffmpeg gives me issues again!
January 15th, 2026
Thank you!

Playing and even converting this has been far from as straight forward as you portray. I can understand that you’ve got some kind of fondness for this codec, but if your goal is to _share_ these audiobooks then you’re doing a poor job of it.
Lots of desktop players that have been updated any time in the past year or so can play the file just fine it seems.
Audiobook apps are much more likely to fail and fall all over themselves still. Particularly if one prefers to stay on an older version of an app with the ever rising enshitification epidemic.
Several tagging/metadata applications wrongfully identify the audio track as AAC-LC causing incorrect behavior though thankfully no crashes thus far.
An up to date ffmpeg (v8.0.1) shat out muxer errors like diarrhea when trying the most straight forward command. Maybe that’s just a skill issue, but if that doesn’t work I have to question any portrayal of ‘_just_ convert it’.
AudiobookConverter (an awful program) does manage to convert it if you’re careful enough setting everything right. That’s something. It must call out to ffmpeg in some more ‘correct’ way or be using something else under the hood.
Thanks for sharing anyway, regardless. I wish you well on your apparent quest to valiantly save 10s of megabytes!

I don’t disagree, and probably in the future I’ll go back to having both the xHE-AAC and AAC-LC versions in the torrent.
This release (and the other 3 that are xHE-AAC only) was a test, which clearly didn’t go well as people don’t seem to be ready yet.
> “Audiobook apps are much more likely to fail and fall all over themselves still. Particularly if one prefers to stay on an older version of an app with the ever rising enshitification epidemic.”
Not really, as support for xHE-AAC has been baked directly into the Android and iOS operative systems, so any app that uses the OS player in the backend (most of them) do play, both on iOS and Android: “xHE-AAC is supported in Android since Android Pie and in iOS since iOS 13.”
https://en.wikipedia.org/wiki/Unified_Speech_and_Audio_Coding
I’ve personally tested Smart Audiobook Player, Voice Audiobook Player and Listen Audiobook player on Android and Bookplayer on iOS (plus many other apps that integrate with Audiobookshelf) and they were able to play xHE-AAC audiobooks.
> “Several tagging/metadata applications wrongfully identify the audio track as AAC-LC causing incorrect behavior though thankfully no crashes thus far.”
The only one I’ve personally used is MP3Tag, which works perfectly. Can you provide a list of tagging/metadata applications that don’t work with xHE-AAC M4B files? That would be useful to have.
> “An up to date ffmpeg (v8.0.1) shat out muxer errors like diarrhea when trying the most straight forward command. Maybe that’s just a skill issue, but if that doesn’t work I have to question any portrayal of ‘_just_ convert it’.”
You’re right, with ffmpeg 8.0.1 if I try to do the re-encoding with
.\ffmpeg.exe -c:a aac -i 13_Unmapped_[B0GFXD58HK]_xHE-AAC.m4b -vn -c:a libmp3lame -b:a 128k 13_Unmapped_[B0GFXD58HK]_test.mp3
I get
“Error submitting packet to decoder: Not yet implemented in FFmpeg, patches welcome”
I built my own version of ffmpeg with libfdk_aac and my own code is based on that, I didn’t check lately if ffmpeg’s base decoder implementation worked correctly.
“AudiobookConverter (an awful program) does manage to convert it if you’re careful enough setting everything right. That’s something. It must call out to ffmpeg in some more ‘correct’ way or be using something else under the hood.”
I’ve never used that tool, but it does appear to be highly starred on github, though the reviews on Steam are mixed.
If you’d like to convert it without issues just get a build of ffmpeg that has libfdk_aac integrated, either by building it yourself through media-autobuild_suite:
https://github.com/m-ab-s/media-autobuild_suite
or get one of the builds that already include it:
https://github.com/AnimMouse/ffmpeg-autobuild
And then convert with
ffmpeg -c:a libfdk_aac -i 13_Unmapped_[B0GFXD58HK]_xHE-AAC.m4b -vn -c:a aac -b:a 128k -map_metadata 0 -map_chapters 0 13_Unmapped_[B0GFXD58HK]_test.m4b
Or perhaps use dBpoweramp as the user above indicated? I haven’t personally used it so I’m unsure if it works as expected or not.
That said, I’d recommend checking if the device you want to play it on supports xHE-AAC, as the listening experience is better (one of the reasons I moved my entire Libation-ripped ABS library to xHE-AAC as soon as support was added).
>”Thanks for sharing anyway, regardless. I wish you well on your apparent quest to valiantly save 10s of megabytes!”
It’s not really about the size, but rather having the highest possible quality version of an audiobook, and in this case that xHE-AAC, which is higher quality and has some interesting features like loudness normalization.
But yeah, I get the point, I’ll go back to sharing both xHE-AAC and AAC-LC for future torrents.
January 16th, 2026
And the worst thing is that ffmpeg has added support for USAC in September 30th, 2024, FFmpeg 7.1 “Péter”…
And ffplay.exe works perfectly for playing the file, it’s when trying to convert that it breaks.
January 16th, 2026
I use Musicolet to play my audiobooks and the file plays, but it’s really choppy and seems like the playback speed is constantly shifting.
Can one of you tech savvy people who managed to convert it to MP4 please re-post this for those of us less capable?
Thanks!
